    A Visit to Crystal Mountain

    The weather has improved considerably and we were able to fly out today to collect more samples. Yesterday, some of us went to explore Crystal Mountain, a 900-foot peak about five miles from Alert that offers an excellent view of the surrounding landscape. Alert is a Canadian military station located in the far north region…

    Tree-Ring Science in a Log Yard?

    The cool, snowy weather really put a crimp in our plans. Dario, Tuncay, Cengis, and others spent two days trying to find potential sampling locations before Nesibe and I arrived. Even though it had been well above freezing during the day and above freezing at night, the snow had only retreated so far in the…

    Ice cores…finally

    Today I got another chance to go out with team CASIMBO to drill ice-cores. The weather was beautiful with no wind, a few clouds, bright sunshine and a balmy temperature of about 5 degrees F. When I first saw sea ice near Alert a few years ago, I was very surprised. It wasn’t anything like…

  • Students. Saturday. Science?

    It’s a Saturday morning, and most kids between the ages of 12 and 14 are sleeping in, off to rehearsals or sports team practice, or grudgingly helping with household chores. At Columbia University, a group of middle-school students are eagerly engaging in the scientific method.

    “I know that I will miss being a student in the MPA-ESP program and working on valuable projects, like the Spring Workshop. Having had the experience of working with my team on a real-life project for our non-profit client has definitely made me feel more prepared for life after graduation,” stated Andrew McCornack, a member…

    Ice-Coring…Almost

    The weather started to get increasingly worse yesterday, with a lot of clouds, low visibility and snow. That, of course, means that we couldn’t go out flying for two days. The forecast for the next 24 hours doesn’t look promising either. But as usual in the Arctic it’s better not to forecast — everything might…
